A Technical Service Bulletin (TSB) is issued by an automobile manufacturer when a specific problem on a vehicle has been identified. It provides the manufacturer's instructions on how to correct the problem.

I think the amplifier is under the front passenger seat. To fix the bluetooth phone connection problem the amplifier must be replaced with a newer one. You will have to take your vehicle to a Lexus or Toyota dealer/service center, give them the TSB number (AU001-04), and request that they replace the amplifier. However, it may no longer be covered under warranty.

I heard to your advise

There is a Technical Service Bulletin on this problem in the 2004 LX470: TSB Audio AU001-04.

"Some customers may experience the Mark Levinson Audio System remaining muted

after ending a phone call using the Bluetooth system. Improvements have been made to

the software inside the Mark Levinson amplifier to remedy this condition.

Applicable Warranty*:

This repair is covered under the Lexus Comprehensive Warranty. This warranty is in

effect for 48 months or 50,000 miles, whichever occurs first, from the vehicle’s

in-service date.

* Warranty application is limited to correction of a problem based upon a customer’s specific complaint."

I had the same problem. I found the TSB and the dealer replace the amplifier under warranty.
